CMC’s range of bow thrusters all feature dual contra-rotating propellers and are suitable for a wide range of uses. They can be fitted to vessels with steel, aluminum or composite hulls.

The use of dual contra-rotating propellers provides at least 30% more thrust from the same power and diameter of a single propeller unit.
